Affinity capture surfaces

Affinity capture is based on the specific binding of a tagged biomoleclule to its receptor. The plate surface is therefore developed with one of the binding pair (the receptor) immobilized on its surface, while the tag is linked to a biomolecule either by chemical coupling or genetic engineering. The tagged biomolecule can then be captured on the plate surface with a high degree of specificity.

Streptavidin- and NeutrAvidin-coated plates for binding biotinylated antibodies or probes for ELISA and other target-specific assays. Biotin-binding plates are ideal for applications when direct adsorption to polystyrene denatures antibodies or the target molecule.
